Insomnia can be very frustrating and we've all been through it—staring at the ceiling in the middle of the night, hoping to catch a few winks before the dim blue light of dawn shows up. Luckily there are ways to improve your sleep. At soon-to-launch startup Casper, co-founders Philip Krim and Neil Parikh have been hard at work testing quantifiable sleep products to find out what makes for a better night's sleep. With Philip's entrepreneurial acumen and Neil's background in robotics with NASA (among other things), the duo hope to help people engineer their slumber. Have a question about sleep or the lack thereof? Philip and Neil will be here for the next hour so ask away.
